Presenting data in a tabular format is a common requirement in many applications. To simplify this task, the DataGridView control offers a comprehensive solution for displaying tabular data within Windows Forms. With its versatile features and capabilities, the DataGridView control serves as a powerful tool for efficient data presentation.

ComboBox to C# DataGridView

The DataGridView control gives the developer the advantage of the collection of cell types which include TextBox, CheckBox, Image, Button, ComboBox, and Link columns. All the columns display particular cell types while they hold diverse formats of data that can be navigated and used accordingly.

The following C# program shows how to add a ComboBox in Cell of a DataGridView control.

using System; using System.Data; using System.Windows.Forms; using System.Data.SqlClient; namespace WindowsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { dataGridView1.ColumnCount = 3; dataGridView1.Columns[0].Name = "Product ID"; dataGridView1.Columns[1].Name = "Product Name"; dataGridView1.Columns[2].Name = "Product Price"; string[] row = new string[] { "1", "Product 1", "1000" }; dataGridView1.Rows.Add(row); row = new string[] { "2", "Product 2", "2000" }; dataGridView1.Rows.Add(row); row = new string[] { "3", "Product 3", "3000" }; dataGridView1.Rows.Add(row); row = new string[] { "4", "Product 4", "4000" }; dataGridView1.Rows.Add(row); DataGridViewComboBoxColumn cmb = new DataGridViewComboBoxColumn(); cmb.HeaderText = "Select Data"; cmb.Name = "cmb"; cmb.MaxDropDownItems = 4; cmb.Items.Add("True"); cmb.Items.Add("False"); dataGridView1.Columns.Add(cmb); } } }

The TextBox column type facilitates the input and editing of text data, while the CheckBox column type allows for the selection of Boolean values through checkboxes. Image columns enable the display of graphical content, Button columns enable interactive button functionality, and ComboBox columns provide a dropdown selection mechanism. Additionally, Link columns offer the ability to incorporate clickable hyperlinks within the DataGridView control.

With these diverse column types and their corresponding cell types, the DataGridView control offers flexibility in representing different data formats and accommodating user interactions. This comprehensive approach ensures that developers have the necessary tools to effectively display and manipulate tabular data.

Conclusion

The DataGridView control is a valuable component within Windows Forms, providing a robust and all-encompassing solution for tabular data display. By offering various column types and associated cell types, it empowers developers to present data in a visually appealing and interactive manner, enhancing the user experience and facilitating efficient data management.
